Deviations from high effort deterred by large enough skin in the game (Kim and Shin (2012), multi-firm version of Holmstrom and Tirole (1997)) where p i p i+1 +(1+b i )w i b i = b r(1+r)i ε (IC)

Financial Shocks in Production Chains 20 Industrial Development How can developing countries with poorly capitalized firms achieve lengthening of production chain? Two hurdles: Working capital to finance the initial triangle of costs Sustaining long production chain Both can be solved if firms have sufficient initial capital (by using IR slack to relax IC) Both are problematic when firms are poorly capitalized
Financial Shocks in Production Chains 21 Comparative Industrial Structure Financial interlinkages in supply chain through accounts receivables and payables may mitigate inefficiency due to bargaining and incentives Efficiency through delayed settlement Possible explanation for why accounts receivable and payable are so large? Downside of delayed settlement is large demands on working capital Equity capital accumulation brings economic efficiency gains
